floor-CLAMP.

To all whom "it may concern:

Be it known that I, WILLIAM H. HOLMES, a citizen of the United States,residing at Proctor, in the county of Rutland and State of Vermont, haveinvented a new and useful Hoop-Clamp, of which the following is aspecification.

This invention relates to coopering, and more especially to hoop clamps;and the object of the same is to produce a foot operated device adaptedto simultaneously serve the dual function of a clamp for holding thelapping ends of the hoop and an anvil upon which the nails driventhrough said ends may be clenched. This object I accomplish by theconstruction hereinafter more fully described and claimed, and as shownin the drawings wherein Figure 1 is a front elevation of this machinecomplete. Fig. 2 is a central vertical section thereof. Fig. 3 is a planview.

In the drawings the numeral 5 designates a standard having a base 6 atits lower end and a longitudinal slot or recess 7 in its upper end, and8 is a foot lever pivoted at 9 to said standard and normally supportedby a spring 10. The numeral 11 designates the face of a curved anvil,and 12 is its upright body connected with said face by several webs 13,the body being secured to the front face of the standard in any suitablemeans as by screws 14 and the curved face or anvil 11 projecting forwardfrom said standard as best seen in Fig. 2. 15 designates a box for nailsor the like, preferably having a hinged cover 16, the whole beingattached to the front of the body of the anvil in convenient positionfor access by the operator. These parts constitute the fixed members ofthe clamp for holding the lapping ends of a hoop, and the face 11 is ofa curvature corresponding with that of the hoop to be nailed.

The moving member of the clamp comprises a curved arm 21 havingdepending from it near its ends two guides 23 which slide behind therear portion of the body 12 of the fixed member, and depending from itscenter and also behind said body 12 a bar 22 which has a foot 23 at itslower end, said foot being connected with the foot lever 8 by means of alink 24. Projecting forward from each end of the arm 21 and facingdownward is a jaw 25 which extends over the anvil 11 and is normallysupported above the same by means of the Specification of LettersPatent. 7 Patented Aug. 29, 191.1.

spring 10. The fixed member and the movable member of the clamp may bothbe of metal, whereas other parts excepting the spr ng may be of wood orany desired mausual; and the size and shape and details of constructionare matters of no moment in this invention.

In operation the hoop (not shown) has its ends brought together andlapped, and then laid upon the anvil ll beneath the jaws 25, after whichby depressing the foot lever 8 the operator moves the movable memberdownward so that the jaws descend upon the ends of the hoop and pressone upon the other and both downward onto the anvil where they areforcibly held. Thereafter, taking some nails from the box 15, he drivesthem downward through the uppermost hoop-end, then through the lowermosthoopend, and finally causes their points to impinge upon the anvil whichturns them aside and clenches them into the inner face of the hoop asthehammer sinks their heads in the outer face thereof. After the lappingends have thus been securely connected with each other, the operatorreleases pressure from the foot lever 8 and the spring 10 causes themovable member -of the clamp to rise so that the jaws 25 release thehoop, and the latter is free to be removed and replaced by another for arepetition of the act just described.

What is claimed as new is:

1. The herein described hoop clamp, the same comprising an uprightstandard having a recess in its face, a fixed member consisting of abody secured to the standard across said recess and a curved anvilprojecting forward from said body, a movable member consisting of anarm, jaws projecting forward therefrom above said anvil, and a bardescending from the arm and slidably mounted in said recess, means forholding the movable member normally elevated, and a lever for overcomingsaid means and depressing the movable member when desired.

2. The herein described hoop clamp, the same comprising an uprightstandard having a recess in its face, a fixed member consisting of abody secured to the standard across said recess and a curved anvilprojecting forward from said body, a movable member consisting of anarm, two jaws projecting forward therefrom above said anvil, and a bardescending from the arm and slidably mounted in said recess, a footlever pivoted to said standard, a spring normally raising the lever, anda link connecting the foot lever with the lower end of the bar, thewhole for use substantially as hereinbefore described.

3. In a hoop clamp, the combination with an upright standard having arecess in its front face, an arm slidably mounted in said recess andhaving a foot projecting forward from its lower end, a foot leverpivoted to the standard, means for normally raising said lever, and alink connecting the latter With said foot; of a fixed member includingan upright body extending across said recess, a curved anvil projectingforward from the upper end of said body, and webs integrally connectingthe latter with said anvil, and a movable member including a curved armconnected to the upper end of said bar and standing in a plane in rearof the body of said fixed member, guides depending from said arm andmoving against the rear of said body, and jaws projecting forward fromthe ends of said arIn across the anvil and normally sustained above andout of contact with the same when said foot lever is elevated.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.

WILLIAM H. HOLMES.
